Ron Vaughn medium block mallets are designed for Ron's Wood Block models W-2, a 7 inch Black Walnut block tuned to about an E natural, and Ron's W-3, a 9 inch Hard maple block tuned to about a C sharp. The MBM-2's are offered in Birch shafts, MBM-2B with Emerald Green band, or Rattan shafts, MBM-2R with Yellow band.
Performance Tip: The MBM-2's are excellent for performance situations where changing mallets in mid-performance is not practical. Of all of Ron's High-Density head mallets, the MBM-2's offer the best overall sound on blocks, (and suspended cymbals), if you have to pick a single pair only. For fast moving pieces requiring a wide range of block sizes and pitches, and maybe a little cymbal/keyboard work, the MBM-2's are a good choice.
The MBm-2's are remarkably versatile in weight and design for many types of Multiple Percussion work, especially where mallet change time is limited.
